Bangalore-based company has found ventilators that can operate without electricity. Corona prevalence is spreading throughout the world. The number of victims is close to 25 lakhs. The death toll has exceeded 1.5 lakh. But the tools and therapeutic tools needed for treatment are not enough. The diagnosis and treatment of coronary artery disease has thus become a major challenge. In this case, Dynamic Tech, a Bangalore based company, has found a cheap ventilator. It costs only Rs. 2,500. NITI Aayog commended the company for being a very important innovation during the crisis.
